The color #0D42A7, a deep cobalt, presents some accessibility challenges, especially when used as a background color for text. Due to its low luminance, it requires careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #0D42A7, lighter text colors such as white or light yellow are generally recommended to meet these contrast requirements.

When using this color for interactive elements such as buttons or links, it is important to provide sufficient visual feedback on hover or focus states. This can be achieved by darkening or lightening the color or adding a border to indicate interactivity, which is very important for overall usability.
